ObjectiveMaxing Shigan Tang， as a traditional prescription for treating pneumonia， has a remarkable clinical effect. This study aims to systematically investigate the molecular mechanisms of Maxing Shigan Tang in treating pneumonia by integrating its structural and transcriptomic data at the target level. MethodsNP-TCMtarget， a developed systematic network pharmacological model focusing on drug targets， was used to mine the effect targets of Maxing Shigan Tang for treating pneumonia based on the transcriptome data. The structural targets of chemical components in Maxing Shigan Tang were predicted based on the structural information. The intersection of effect targets and structural targets was taken as the direct targets of Maxing Shigan Tang for treating pneumonia， and the remaining effect targets except direct targets were taken as indirect targets. Finally， functional enrichment analysis was performed on these targets to explore the molecular mechanism of Maxing Shigan Tang in treating pneumonia. ResultsA total of 1 604 effect targets and 816 structural targets of Maxing Shigan Tang for treating pneumonia were identified. Maxing Shigan Tang exerted its therapeutic effects through 164 direct targets and 1 440 indirect targets. The functional analysis of 1 604 effect targets predicted 19 significantly enriched pathways. Comprehensive analysis of these pathways showed that these targets were mainly linked to immune and inflammatory responses， such as cytokine-cytokine receptor interaction， necrosis factor （NF）-κB signaling pathway， and helper T cell 17 differentiation. ConclusionFocusing on the hierarchical feature of drug targets and the structural and transcriptomic data， this study systematically reveals the path of herbal component-direct target-indirect target-biological effects of Maxing Shigan Tang in treating pneumonia.

Objective:To evaluate the efficacy and safety of 532-nm picosecond laser in the treatment of early-stage facial seborrheic keratosis.Methods:A total of 95 patients with early-stage facial seborrheic keratosis were prospectively enrolled from the Department of Dermatology, General Hospital of Ningxia Medical University between December 2020 and September 2022. All the patients received a session of 532-nm picosecond laser treatment, and were followed up for 6 months. A 4-point scale was used to evaluate the overall improvement of skin lesions for assessing the clinical efficacy. A VISIA skin detector was used to quantitatively determine the characteristic counts, absolute scores, and percentiles of brown spots before and after treatment, and the paired sample t-test was used to compare the quantitative indicators of brown spots before and after treatment. The patients′ pain grades were evaluated, and adverse reactions were recorded. Results:All the 95 patients with early-stage facial seborrheic keratosis received a session of 532-nm picosecond laser treatment, and completed a 6-month follow-up. All the patients achieved over 25% regression of skin lesions in the treatment area, of whom 10 received mild improvement, 17 received favorable improvement, and 68 received marked improvement, with the response rate being 89.47% (85/95). The examination with the VISIA skin detector showed that the characteristic counts (195.19 ± 51.06) and absolute scores (28.80 ± 6.20 points) of brown spots significantly decreased, while the percentiles of brown spots (38.48% ± 10.80%) significantly increased at 6 months after treatment compared with the corresponding baseline indicators (211.48 ± 50.94, 35.16 ± 6.84 points, 30.61% ± 10.27%, t = 12.73, 16.90, -15.73, respectively, all P < 0.001). All the patients experienced varying degrees of pain during the treatment, with the pain scores being 2 - 6 (3.64 ± 1.67) points, but all of them could tolerate the pain and completed the treatment. Temporary postinflammatory hyperpigmentation and hypopigmentation occurred in 9 (9.47%) and 4 (4.21%) patients respectively, and the skin color restored to normal during the 6-month follow-up. Conclusion:The 532-nm picosecond laser was safe and effective for the treatment of early-stage facial seborrheic keratosis.

Myocardial infarction （MI） is a common cardiovascular disease in clinical practice and one of the main causes of cardiovascular mortality. Its pathogenesis is complex and associated with oxidative stress reactions. Nuclear factor E₂-related factor 2 （Nrf2） is a key factor in regulating oxidative stress reactions. It can regulate the expression of heme oxygenase-1 （HO-1）， playing a role in maintaining the oxidative-reductive homeostasis in the body. During the course of MI， the biological activity and levels of Nrf2 and HO-1 decrease， leading to weakened tissue antioxidant and anti-inflammatory capabilities， endothelial damage in myocardial blood vessels， release of vascular cell adhesion factors， and impaired endothelial function. In recent years， many basic research studies have explored the role and mechanisms of traditional Chinese medicine （TCM） in treating MI by modulating the Nrf2/HO-1 signaling pathway. The results have indicated that the Nrf2/HO-1 signaling pathway is an important potential target for TCM in the treatment of MI. This article reviewed the mechanism of the Nrf2/HO-1 signaling pathway in MI and the research progress of TCM in targeting and regulating this pathway， aiming to provide a theoretical basis for the prevention and treatment of MI and further drug development.
